Title: Method for interactive false checking of a product by using colored 2 dimensional bar codes and a system for performing the same

Abstract: A method for interactive false checking of a product by using colored 2 dimensional bar codes comprises the steps of (a) generating a unique colored forgery-proof bar code 40, a fixed data 41 and a 2D variable bar code 42 by inputting a product related data and generating a database in the auto-bi-directional comparison and the responding system 6; (b) printing a colored 2D variable bar code containing the product data by a digital printing device; (c) printing the colored 2D variable bar code on a tag; (d) a consumer scanning the 2 dimensional variable bar code so as to get the product data which transferred to the system for comparison; (e) after comparison, a comparison result being transferred to the consumer's handset; and (f) the phone numbers of the phone or handset of the consumer for future using. A system for performing the same is also provided.
